Wigan's 4-0 Barclays Premier League humbling at the hands of Arsenal was a big disappointment to manager Roberto Martinez after a high of last weekend's win at Sunderland.
Mikel Arteta opened the scoring in the 28th minute and Thomas Vermaelen made it two a minute later, while second half goals from Gervinho and Robin van Persie accurately reflected the visitors' dominance.
He said: "I thought we started really well. The first 10 or 15 minutes we created problems and I felt we were going to grow really well into the game.
"Everything you do in a football game is to score goals, and in the same manner conceding the goals we conceded today makes performances very difficult.
"The two goals are really soft and they are really close to each other, and I felt that affected us too much. That's probably the real disappointment.
"We all know Arsenal have got a real quality squad and real experience but giving them a two-goal cushion helped them to use their experience and control the tempo of the game, and we made it a little bit easy."
